Move ion-item closer to each other

I am trying to move two ion-item closer. I have taken out the padding. Now what else can I do?
I have tried line-height: 80% but it has not effect.

<ion-item  no-padding style="line-height: 80%;">First one</ion-item>
<ion-item  no-padding style="line-height: 80%;">Second one</ion-item>
